How this service works
Call when an agent needs whether an 8-digit EAN passes Luhn. Exact $0.008 USDC. Prefer unpaid POST /v1/sandbox/check-ean-8 first.
Output
Returns a boolean pass/fail result indicating whether the submitted 8-digit EAN barcode satisfies the Luhn check digit algorithm, confirming its structural validity as a legitimate EAN-8 code.
Example use cases
E-commerce product listing validation
“Before I add this product to our catalog, can you verify that the EAN-8 barcode 40170725 passes the Luhn check so I know it's a valid barcode?”
Barcode scanner data quality check
“My scanner just read EAN-8 code 12345670 — can you confirm whether it's a valid barcode according to the Luhn algorithm before I log it in our inventory system?”
Bulk product data pre-flight check
“I'm about to submit a new product with EAN-8 code 73513537 to our supplier portal — can you validate the check digit on that barcode first?”
